Lift Kit, and rear locker for my 1979 Chevy Cargo Van!

So I got this cool but a little rusty 1979 Cargo van. She is in pretty good shape, but she has a little bit of cancer here and there, but she is going to be my hauler, but I want her just little bit more rough for winter since she is not a 4wd. Anyone have any suggestions on these beast. I can not find a lot of info on this van.
